From Tim Vines
I was very impressed with your announcement that data will now be transmitted
through water on the same frequency that dolphins use
(This Week, 27 June, p 14).
It strikes me that this is somewhat analogous to cetaceans using huge Tannoy
systems to transmit their digitised data over the land.
Has the Newcastle team considered the impact of their invention on the rather
sensitive ears of dolphins and friends?
